If he notices, mine will ask if I want assistance grounding and regrouping. Only once have we had a full session with me completely dissociated. I had to come to therapy straight from court and could not get back from being completely cut off from all emotion. I thought it was pretty unproductive and have made sure to never schedule things that way again. However the point of that little story was that he asked if I wanted assistance and that very cold, intellectual part of me told him to **** off and stay out of my head. He just said okay and we went on from there.
